Stathis, and listers,
I cannot help: I read the text. (Not always, sometimes it seems too obtuse
for me even to 'read' it).
The Subject? ( Consciousness = information )
what happens to that darn 'information'? Oops, 'you' are AWARE of it!?
Meaning: you *DO* something with it (to "be - become?" aware). Who???? By
what factor (energy, process, function, etc.)? By what (who's??) initiation?
Oops: by *computation of course. *
Refer all the above questions to 'computation and add: who (what?) is
providing the computer? (St.: store-bought computer - is it a binary
embryonic, or a more advanced one, maybe an (unlimited!) analogue - whatver
that may be).
forget all those questions and live happily in Wunderland.
The nature of an applicable "INFORMATION" is still undecided. The 'bit' has
to be part of a program to make sense (to have 'meaning' - another term to
be questioned.) Maybe in a conscious software? (robotic?)
*Information and its meaning* are concept (observer?) related.
I am hung up on 'having a computer' and 'computation' (available?) that
still does not *DO *the computation, not even *operate* the computer.
And please, say 'energy' only, if you can tell what it is (not what it does
or how it can be measured). And the construct(?) that includes it all.
I am also hung up with 'function' (activity) and the 'observer' (self, "I")
what seems to be so natural in the nth level consequence using them.
